2 - Compose Key Mode.
Ubuntu also has a composition table, a mapping from sequences of keys called key chords to individual special characters. The composition table for Ubuntu can be found here https://help.ubuntu.com/community/GtkComposeTable. For frequent use of special characters, composition shortcuts is a faster alternative.
